1. A 380 / 220 V r.m.s. 3-phase 4-wire circuit carries loads of 8 + j8.1 ohm; 4 + j4.1 ohm; and 2 +j2.1 ohmin the three phases respectively. The length of the circuit is 100 m, and the resistivity of the phase conductors is 0.0005 Ω/m. The neutral conductor is of the same size as the phase conductors. a) Select a reference angle 0for the first phase. Then write down the three phase voltages in both polar format and complex number format. b) Make appropriate assumptions, and take temperature effects on resistance is insignificant. Calculate the currents in the three phases. (Note: Determine conductor resistance, and apply Kirchhoff’s Voltage Law) Based on the result, suggest a main switch rating for the circuit. c) Show your preferred direction of neutral current in a diagram, and then determine its value. (Note: Apply superposition principle, and Kirchhoff’s Current Law) Use its magnitude to show that in this circuit, the unbalanced load may increase the voltage drop in some of the phases. (Note: Also observe the common volt drip in neutral) State your assumptions, if there are any. d) Suddenly the neutral wire of the circuit is broken. Estimate the new currents in the first phase, i.e. Phase L1. State your assumptions, if there are any.

You have an AI player in an RTS game that occasionally needs to send scouts out onto the map to perform reconaissance. Designers want each scout to move around semi-randomly, exploring various parts of the map, particularly those that have been seen the least recently. Assume that the game is grid-based and has a fog-of-war feature. Also assume that the scouts are very cheap and dispensable, and it's OK for them to walk into the enemy base or other dangerous areas. How would you implement the system to decide where the scouts should go? What sort of data structure do you need to support this? How can you ensure that the scouts do a good job of exploring the map thoroughly? What are the performance characteristics of your approach? Is there any risk of scouts getting stuck trying to go somewhere that isn't even accessible?
